In English, Wikipedia says these started out as superscripts: 1 st, 2 nd, 3 rd, 4 th, but during the 20 th century they migrated to the baseline: 1st, 2nd, 3rd, 4th. So the practice started during the Roman empire, and probably was continuously used since then in the Romance languages. I don't know when it was adopted in English. Here is a ...

2014年8月23日 · However, as in the second and third examples, the rd & st simply come from the right-end of the word for the ordinal number: 3 rd: thi rd. 301 st: (three-hundred-) fir st (shouldn't that be 301 th?, I'm not going there).

He was the first person to land on the moon. The green Camaro was the first car over the finish line. With that, they became the third university to have over 1000 students. When the ordinal number is used as an adverb, however, no article is called for: The USA is ranked first in the survey. I finished third. John went fifth.

Consider this century. In English, it is referred to as the twenty-first century, even though it starts with 20. That's because if you count backwards to the start of the Christian time labeling, the first years marking from when Jesus Christ was supposed to be born is called the 'first century' but isn't the years 101-200 but rather 1 through 100.
